KLUsoN MUSIC STAND Filed April 10, 1936 o d M f'.nlmll alllllnml' Patented May 4, 1937 UNITED STATES PATENT ortiesvApplication April 10, 1936, Serial No. '73,639V i g claims. v(c1. i5-121) The present invention relates `generally to stands. Moreparticularly the invention relates to that type of stand which isadapted to be used by musicians to support or holdbook or sheet musicand comprises (l) a standard which is provided at its lower end withlegs for supporting it in an upright or vertical position and has abracket pivotally connected to the upper end thereof; and (2) a rackwhich is detachably connected to, and is supported for vertical angularadjustment by, the bracket at the upper end of the standard andcomprises a one-piece horizontally` extending angle bar-type ledgeforming bottom member and a pair of laterally spaced collapsible linkformed music supporting frames.

One object of the invention is to provide a music stand of this type inwhich the frames of the rack are so constructed and are pivotallyconnected to opposite ends of the top flange of the bottom member insuch manner that when they are swung into their collapsed position onefits against and is substantially coextensive with the front face of thetop web and the other ts against and is substantially coextensive withthe back face of said top web of the bottom member andis in lappedrelation with respect to the one frame and the rack as a whole is henceeX- tremely compact and occupies but a minimum space when the frames arein their collapsed position.

Another object of the invention is to provide a music stand of the typeunder consideration in which the braket for supporting or carrying therack so that it may be swung or adjusted vertically into differentpositions comprises a rec-l tangular plate which underlies the centralportions of the inner side links of the collapsible frames and thedetachable connection between the rack and the bracket is in the form ofupwardly extending outstruck tongues on the side margins of the plateand tongue receiving slots in the inner side links of the frames.

A further object of the invention is to provide a music stand of thetype and character last mentioned in which the central portion of thetongue-equipped plate of the bracket is raised with respect to the sidemargins and forms a spacing member which tsbetween, and abuts againstthe inneredges of, the inner side links of the frames and servesrtoprevent the frames from swinging or tilting sidewise out of their normalposition when the rack is in connected relation with the bracket.` i

A still further object of the invention is to provide a music standWhich consists of but a small number of parts, may be manufactured atalowand reasonable cost, and -ls generally an Vimprovement upon andsimpler in construction than previously designed stands of the samegeneral type. f

Other objects of the invention and the various advantagesand'characteristics of the present music stand will be `apparent from aconsiderae tion of the followingV detailed description.

In the drawing which accompanies and forms a part of this specificationor disclosure and in which like numerals of reference denotecorresponding parts throughout the several views:

Figure 2 is a front view showing the rack detached from the bracket atthe upper end of the standard and the frames in partially collapsedposition;

Figure 3 is an enlarged section taken on the line 3 3 of Figure 1 andshowing in detail the construction and design of the tongues and slotswhich form the detachable connection between the rack and the bracket;and

Figure 4 is an enlarged section taken on the line 4--4 of Figure l andillustrating in detail the cross-sectional construction ofthe plate ofthe bracket and the manner in which the central raised portion thereoflits between the inner side links of the frames and serves to hold theframes against relative tilting or swinging movement when the rack is inits fully extended or normal position and in connected relation with thebracket.

The stand which is shown in the drawing constitutes or represents thepreferred embodiment of the invention and is adapted primarily for useby musicians in that it is designed to support in an elevated andsubstantially vertical position book or sheet music. It is formed ofmetallic parts and consists of a standard 5, a

bracket 6 at the upper end of the standard, and a music supporting rack'l on the bracket. The standard 5 is adapted to be supported or held ina vertical or upstanding position by means of legs (not shown) at thelower end thereof. The bracket 6 is pivotally connected to the upper endof the standard,v as hereinafter described, and serves to support therack 'l so that it may be tilted or swung vertically into diiierentpositions.

The rack I consists of a horizontally extending angle bar type bottommember 9 and a pair of laterally spaced or positioned rectangularlinkformed frames S and i0. The bottom member 8 forms a ledge on whichthe rack supported music is adapted to rest and consists of a top web IIand a bottom web I2. The web II is formed integrally with and extends atright angles to the bottom web I2. The frame 9 is associated with oneend of the bottom member 8 and comprises an outer side link I3, an innerside link I4, and a cross-link I5. The side links I3 and I4 are arrangedin parallel relation and extend upwards and at right angles with respectto the bottom member 8 when the frame 9 is in its extended or normalposition. The lower end of the outer side link I3 ts against the backface of said one end of the top web I I of the bottom member 8 and isconnected pivotally to the top web by means of a rivet I6. The innerside link I4 is the same in length as the outer side link I3 and thelower end of the inner side link I4 fits against the back face of thecentral portion of the top web II and is pivotally connected to the webby a rivet I'I. The cross-link I5 extends parallel to the bottom member8 of the rack and extends between and is pivotally connected by rivetsI8, I8a to the upper or distal ends of the side links I3 and I4. Byreason of the fact that the links I3, I4 and I5 of the frame 9 areconnected pivotally, as hereinbefore described, the frame is adapted tobe swung toward the opposite end of the bottom member 8 into a collapsedposition wherein the links thereof are in longitudinal alignment and tagainst or lap the back face of the top web II of the bottom member 8.The combined length of the outer side link I3 and the cross-link I5 issubstantially equal to the length of the bottom member 8 and thereforethe frame 9, when in its collapsed position is no longer than and doesnot project beyond the bottom member 8. The frame 9 in addition to theside links I3 and I4 and the cross-link I5 comprises a pair of links I9and 20, and a pair of links 2| and 22. The link I9 underlies and extendsparallel to the cross-link I5 and the link 20 is positioned inwardly of,and is parallel with, the outer side link I3. The outer end of the linkI9 is pivotally connected by a rivet 23 to the central portion of theouter side link I3 and the other or inner end of the link i9 ispivotally connected by a rivet 24 to the lower end of the link 20. Theupper end of the last mentioned link lits against the front face of thecrosslink I5 and is pivotally connected by a rivet 25 to the centralportion of the cross-link. The links I9 and 20 assist the side links I3and I4 and the cross-link I5 in forming a backing or support for therack supported music and are positioned or disposed in longitudinalalignment and in lapped relation with respect to the back face of thetop web II of the bottom member 8 when the frame 9 is in its collapsedposition. The links 2I and 22 also assist the side links I3 and I4 andcross-link I5 in forming a backing for the rack supported music and areadapted when the frame 9 is in its collapsed position to lap the backface of the top web II of the bottom member 8. The link 2I is disposedbeneath and extends parallel to the cross-link I5 and the centralportion thereof is pivotally connected by way of a rivet 26 to thecentral portion of the outer side link I3. As shown in Figure l of thedrawing, the link ZI is positioned or located at a point one-third oithe distance from the rivet i8 to the rivet I6 and the link I9 ispositioned midway between the link 2I and the rivet I6. The centralportion of the link 22 ts against the back face of the cross-link by arivet 2l which is located at a point one-third of the distance from therivet I8 to the rivet |89. The lower end of the link 22 is pivotallyconnected to the inner end cl' the link 2l by a rivet 28. The outer endsof the links 2l and 22 project respectively beyond the outer side linkI3 and the cross-link I5 when the rack 9 is in its normal or extendedposition, as shown in Figure 1, serve to support sheet music which islarge in size. The link 20 is located midway between the link 22 and theinner side link I4. The rivets I8, 28, 24 and Il are in alignment, thatis they are disposed in the same plane and hence the frame 9 collapsesfreely.

The frame I9 of the rack 'I is associated with the opposite or other endof the bottom member 8 and comprises an cuter side link 29, an innerside link 30, and a cross-link 3l. The links 29 and 39 are spaced apartthe same distance as, and are equal in length to, the links I3 and I4 oithe frame 9 and extend upwardly and at right angles with respect to thebottom member 8 of the rack v'I when the frame is in its extended ornormal position. The lower end of the outer side link 29' fits againstthe front face of the top web Il of the bottom member 9 and is pivotallyconnected to said-other or opposite end of the top web by means of arivet 32. The lower end of the inner side link 39 is spaced a smalldistance from the inner side link I4 of the frame 9, as shown in Figurel. It fits against the top web I I of the bottom member 8 and ispivotally connected to the top web by means of a rivet 33. The crosslink3l is the same in length as the cross-link I5 and extends between and ispivotally connected by rivets 34 to the upper or distal ends of the sidelinks 29 and 39. As a result of the arrangement of the side links 29 and30 and the cross-link 3|, and the manner in which these links arepivotally connected, the frame I9 may be swung towards the frame 9 intoa collapsed position. When the frame is in its collapsed position theside links 29 and 3D and the cross-link 3l fit against the front face ofthe top web II of the cross-member 8 and are in lapped relation withrespect to the links of the frame 9. In addition to the side links 29and 30 and the cross-link 3l, the frame I9 comprises a pair of links 35and 36 and a pair of links 3l and 39. The links 35 and 38 correspond tothe links I9 and 29 and are pivotally connected to the outer side link29 and the cross-link 3i in the same manner as the links I9 and 29 arepivotally connected to the outside link and cross-link of the frame 9.The links 3l and 38 correspond to the links 2| and 22 of the frame 9 andare arranged in similar relation. The combined length of the outer sidelink 29 and the cross-link 3| is slightly less than the length of thebottom member 3 ol the rack 'I and as a result the frame I9, when in itscollapsed position, does not project beyond the ends of the bottommember 8. By reason of the fact that the side links of the frame Ill litagainst the front face of the top web II of the bottom member 3 and theside links of the frame 9 t against the back face of the top web theframe Il! is forwardly positioned with respect to the frame 9 andneither frame interferes with the other when the rack l' is collapsed.

The bracket 9 at the upper end of the standard 5 consists of a pair ofside plates 39 and a tcp plate 49. The side plates are substantiallysemicircular and are positioned in laterally spaced relation and onopposite sides of the extreme upper end of the standard 5. As shown inFigures 3 and 4 the standard is formed of rod type stock and the upperend thereof is flattened so that the side plates 39 of the bracket 6 fitflatly thereagainst. A rivet or stud 4I extends through the side platesand the attened upper end of the stand and connects the bracket to thestandard so that it, together with the rack 1, may be swung or adjustedvertically into different angular positions. 'I'he straight portionsofthe side plates are bent outwards or sidewards in opposite directionsin order to form ears 42. in iits against these ears, as shown in Figure4, and is xedly secured to the ears by means of rivets 43.` The bracket6 is releasably locked in its various adjusted or tilted positions bymeans of a bolt 44 and a'wing-nut 45. The bolt is located beneath thestud 4| and comprises an externally threaded shank 46 and a head 4l. Theshank extends througha hole l48 in the attened upper end of the standard5 and arcuate slots 49 in the side plates `39 of the bracket 6. The

head 4l of the bolt ts against one of the sidev plates and the wing nut40 is mounted on the threaded portion of the shank of the bolt and whentightened operates to clamp the side plates to the flattened upper endof the standard. The central portions of the inner side links I4 and iit `of the collapsible frames are adapted to rest on the side margins ofthe top plate 40 of the bracket 6 and the rack is connected to thebracket by means of upwardly extending tongues 50 on the top plate ofthe bracket and slots` 5| in the central portions of the inner sidelinks. The tongues 5B are formed integrally with, and struck outwardsfrom the side margins of the top plate of the bracket and are adapted toextend through the slots 5| and form hooks f or supporting the rack.Preferably there are two tongues on each side margin of the top plateand these tongues, as shown in Figure 2, are positioned one above theother.v 'Ihe slots 5| extend longitudinally or lengthwise of the innerside links of the frames 4o and have enlarged lower ends to permit ofready tilting of the frames. The central portion of the top plate 40 ofthe bracket is raised with respect to the side margins and forms aspacing member which flts between and abuts against the inner l sideedges of the inner side links of the frames Cil and serves to preventthe frames from swinging or tilting sidewise out of their normalposition when the rack is in connected relation with the bracket.Preferably the central portion of the top head of the bracket is raisedto such an extent that the top or front face thereof is flush with theupper faces of the links I4 and 30, as shown in Figure 1. As a result ofraising the central portion of the top plate and forming the spacingmember between the inner side links of the collapsible lframes 9 and l0a recess 52 is formed in the bottom of the plate. The ears 42 on theside plates 39 of the bracket fit within this recess, as shown in Figure4.

When it is desired to dismantle the stand the y rack 1 is disconnectedfrom the bracket 6 by sliding or moving it upwards in order to disengagethe tongues 50. After release of the rack the frames 9 and l0 arecollapsed by swinging Athem towards one another into a position where-Thecentral portion of the top plate the stand the frames 9 and I0 areswung upwards into their extended or normal position (see Figure 1) andthe rack is then applied or connected to the bracket by inserting thetongues 50 through the slots 5| and into hooked relation with respect tothe inner side links of the frame. When the rack isin connected relationwith the bracket Vtheraised central portion of the top plate of thebracket iits against the` inner edges of the inner side links of theframes and prevents the frames from swinging or tilting sidewise ofltheir normal position as heretofore pointed out. In

`order angularly to adjust the rack when the rlatter is connected to thebracket, it is only nec-` essary to loosen the wing-nut 45 vand thenswing the rack together with the bracket into any desired position.

V The herein described music stand consists of but a small number ofparts and hence may be manufactured at a low and reasonable cost. Due tothe construction and arrangement of the collapsible frames the rack whendisconnected from the bracket and collapsed occupies but a small spaceand may be conveniently carried or transported from place to place.

The invention is not to be understood as restricted to the details setforth, since these may be modied within the scope of the appendedclaims, without departing from the spirit and scope of the invention.
